Applications
· Pulling small diameter conductors on crossarm mounted straight poles
· Overhead transmission and distribution line construction
· Applications where maximum angle iron <90°
· Stringing requiring stable dual-sheave cable guidance
· Utility line maintenance and installation
Product Advantages
· Double Sheave Stability — Dual sheave provides superior cable guidance and stability, preventing conductor twisting during pulling operations.
· Ultra-Lightweight — Only 1.1-4KG, significantly reducing handling fatigue and simplifying installation at height.
· Wide Conductor Compatibility — Accommodates 25mm to 400mm conductors covering distribution and transmission applications.
· Ball Bearing Smooth Operation — Sealed ball bearings ensure low-friction rotation, reducing pulling force requirements.
· Dual Material Options — Aluminum sheave for durability; nylon sheave for superior cable protection.
· Galvanized Steel Frame — Hot-dip galvanized construction for excellent corrosion resistance.
Frequently Asked Questions (FAQ)
Q: Maximum angle?
A: Designed for max angle iron <90°. For larger angles, use our corner stringing block series.
Q: SHC vs SHCN difference?
A: SHC: aluminum sheave for durability. SHCN: MC nylon sheave, lighter and gentler cable handling.
Q: OPGW use?
A: Nylon sheave variants suitable for smaller OPGW. Consult our technical team.
Q: Mounting options?
A: Crossarm mounting on straight poles. Specify hanger type when ordering.
Q: MOQ?
A: Standard MOQ is 1 SET.
